2019 Kinetic-One K1-50/50c Carbon wheels (alloy braking)




INTENDED USE: This is the new lighter version of our "Best-selling Multi-functional Road/Tri carbon CLINCHER wheelset.

With its 23mm wide rim with ALLOY braking surface this wheelset is ideal for Time Trials, Triathlons, and also spot-on for all but the windiest of sportives/road riding and bunch racing. If you need one set of all-purpose carbons then these (or the new 58c's) are the one's to go for!

With alloy braking surfaces you don't need special brake pads and braking is better than with Full-carbon clinchers (particularly on very long descents)

Your wheels will be hand built to order here in the UK by Andy Morgan, owner and founder of k1 wheels. Turnaround time is most often 7-11 days. (current build times are shown at checkout).

Offered With Full 2 Year Warranty Plus A 14 Day "No Quibble Returns Policy" - If You're Not In Love With These Wheels The Moment You Get Them Just Send Them Back For A Refund Any Time Within 14 Days Of Receipt.

These are our stunning K1 Carbon 50c section 700c clincher wheels (for inner tubes and tyres). For Road or Time Trial or Tri bikes. They have alloy braking surfaces. This is the newest version of our best-selling carbon wheels - Includes lovely new 20/24 spoke choices - some lighter, some more aero, and some in superb new colours to make your bike simply stunning!

We can supply them with a range of clincher tyres - NOW INCLUDING what we reckon is the fastest all-round clincher combination known to humankind: This is the
Conti GP5000 tyres, paired with latex inner tubes. The combination of rolling resistance tests and formal aerodynamics assessments affirms this is the best way to go for all out speed. And when we say "all-round" we mean for real world riding. There are slightly faster tyres ... but they won't last 5 minutes on UK roads! (The GP5000's have puncture protection and are strong as well as blisteringly fast).


The K1-50c wheelset is aimed at Triathletes, Roadies and Time Triallists, where aero is king but you don't want to add the weight and the more challenging handling of deeper rims to your bike - We've also designed them to be a super-tough "investment" wheelset. We believe carbon wheels should be as strong as alloy wheels. 

The 50's are built around our modern "semi U" shaped structural carbon semi-toroidal aero rim. designed to run best with 25c to 40c wide tyres but will also run 23c tyres fine). The rim is designed to cut through the air going forward, whilst maintaining a superb lateral integrity to cross-winds across a full range of wind "yaw" angles.

Unlike the vast majority of alu-carbon deep-section aero wheelsets, the K1-50c's are also designed to be super-strong. Perfect for racing and still strong enough to train on. Lighter wheels are available of course. With the 50’s we  prioritise strength and durability ... as this is what we have become known for! (We do of course offer some superb weight saving upgrades too).  We also wanted to keep it simple and versatile! The inclusion of an alloy braking surface means you can use your K1 wheels without having to use carbon specific brake blocks. This is a massive benefit for many riders.

A friend put me onto this brand and I plumped for their carbon wheels after several useful email exchanges. My wheels are now a year old and I am very pleased with them. Deservedly 5***** in my opinion.

Having previously bought a Kinetic-one bike it seemed a logical upgrade to go for these wheels. (They were about half the price of the Reynolds wheels they also do and I wasn''t sure I''d notice the difference to be honest - so i thought i''d save myself almost a grand and buy these!) They are Superfast wheels and very strong.

I first contacted Andy with may questions about his wheels and it wasn't long before he put my mind at rest. I was so impressed with the amount of knowledge he had I didn't hesitate to purchase a pair of carbon wheels with alloy brake surface. The wheels are just great and a big improvment over my fulcrum racing 3's I had. They are stiff with no flex espeically up the hills. They roll fantastically and what surprised me the most was how much better they were up the hills too. The service is second to none and Andy was always there if I had anything to ask. Cracking wheels considering the price and great looking to. Oh and very light too!!! Thanks again Andy.

I decided on the K1 50s and the intro offer was really good value. The wheels perform brilliantly. Really smooth, stuff and cornering feels great. After a couple of weeks I found one of the spoke nipples was loose. I emailed Kinetic one and they had the wheel picked up quickly. Few days later it was back with me and all sorted. Communicstion was great, and I'd go as far as saying their customer service was just as good as their wheels. I would recommend these wheels to anyone who wants great performance, great looks and a fantastic price. Very very happy.

Just wanted to pass on more thanks to you! I completed the iron distance Outlaw triathlon on Sunday, in the most horrific conditions! I saw plenty of people blown clean off their bikes, as well as many more blown off course. I however was very happy with my medium section wheelset! Just as you advised and predicted, they were a perfect compromise for when you only have one wheelset. No complaints whatsoever from me. As and when I'm in need of another wheelset, I won't be looking anywhere else.

Lovely self assured wheels that roll brilliantly

I love the wheels. They are great value for money and after getting to stick 60 miles into them over the weekend they are exactly what I was looking for. Aerodynamic enough to cut through strong winds and light and stiff enough to glide up the Welsh hills and respond when I put the hammer down. Brilliant set of wheels.
